Valen has been Hydra's pet for years. As the Avengers take down base after base, they find the tiny, defenseless looking girl. Only she is far from that. - This is an alternate universe story. It does not follow any specific timeline.

-"I never had a mother. Just a monster in disguise, thats all I had." -"I love you." -"You can run all you want, but there all ways comes a point when you can't run fast enough." -"My savior. Y/n, you are my saviour." ================== **This is made up, so The Maximoff twins are growing up with the Avengers and were not found in AoU, and Thor Ragnarok hasn't happened. {Ouuu that's a spoiler!}

COMPLETE | She is the Avengers chief physician... and also happens to be an ex assassin.
